I'm tinkering with an interesting couple of builds for an 1850 tournament coming up and I'm torn between a few options I can do, limited to 1 CAD and/or 1 ally detachment (Chaos doesn't have any really good Formations besides the Helbrute ones, but I lack those).

#1) AIRFORCE (CSM/Daemons ally)
Belakor
CSM Tzeentch Prince/Wings/Armor/Familiar/Burning Brand/Mastery 3
Heldrake (Baleflamer)
Hellblade with Hellstorm Autocannons
3 Nurgle Obliterators VOLTW
2 x 10 Cultists

Nurgle Daemons Prince/Wings/Armor/Mastery 3/2 Greater Rewards or 1 Exalted 1 Lesser
Blight Drone
3 Nurglings

#2) TIDE OF SPAWN (Crimson Slaughter/CSM ally)
Nurgle Biker Lord/Daemonheart/Sigil/Fist/Claw/Blights/Melta Bombs/Mutation
Sorcerer/Jump Pack/Mastery 3/Sigil/Balestar of Mannon/Combi-melta/Melta Bombs
2 x 5 Nurgle Spawn
Heldrake
1 Nurgle Oblits
2 x 5 CSM (one melta gun/one plasma gun)

Jugger Fury Axe Lord/Sigil/Melta Bombs/combi-melta/Mutation
5 CSM/Flamer
5 Spawn
3 Nurgle Oblits/VOLTW

#3) BALANCED? (Crimson Slaughter/Daemons ally)
Belakor
Sorcerer/Terminator/Mastery 3/Balestar of Mannon/Melta Bombs
Dreadclaw
Hellblade/Hellstorm ACs
3 Nurgle Oblits
5 CSM/Melta Gun/Combi-melta/Melta bs/Rhino w Havoc launcher, dozer, dirge
5 CSM/Plasma Gun/Combi-melta/Melta bs/Rhino w Havoc launcher, dozer, dirge

2 JuggerHeralds of Khorne (1 w Exalted, 1 w Greater/lesser)
8 Flesh Hounds
1 Tzeentch Herald/Mastery 3
10 Horrors

Hard to say what one will run into over 5 games with all the crazy cool armies people can field. I think the Spawn list would be the most fun to use but of course they have no saves! The Airforce could be pretty strong, just low model count could hurt, psychic stuff isn't as fun I don't think though. The last list narrowly won vs a Draigostar, I think I could fit a Heldrake in there instead of the Hellblade if I ditch some Rhino and CSM upgrades.

Any thoughts?
